METHOD FOR SELECTIVELY SETTING DROPWISE CONDENSATION ON A CONDENSATION SURFACE BY MEANS OF ION IMPLANTATION

摘要

The present invention relates to a method for selectively setting dropwise condensation on a surface (1) of a substrate (2) and to a substrate that is structured on its surface by this method. This involves directing an ion beam (3, 3') onto the surface (1) of the substrate (2) for the implantation of ions into the surface (1) and a resultant structuring of the surface (1). The ion beam (3, 3') impinges on the surface (1) at an angle that is inclined by between 30° and 80° with respect to a normal (4) to the surface. The surface (1) is structured by the ion beam (3, 3') in such a way that drops (7, 7', 7'') of a liquid precipitate on the structuring of the surface (1) during the dropwise condensation.
